dc.description.abstractLyngbya wollei (Farlow ex Gomont) Speziale and Dyck is a common mat-forming benthic cyanobacterium from freshwater habitats. We found that two populations from southeast Queensland (Australia) produce the potent cyanotoxin cylindrospermopsin (CYN) and its analogue, deoxy-cylindrospermopsin (deoxy-CYN). The highest concentrations in environmental samples were 20 and 550 姠g-1 dry weight for CYN and deoxy-CYN, respectively. A sub-sample maintained in culture for over 16 months yielded concentrations of 33 and 308 姠g-1 dry weight for CYN and deoxy-CYN, respectively. The concentration of deoxy-CYN in L. wollei was 10-300 times higher than CYN, suggesting that, unlike many other CYN-producing cyanobacteria, the primary compound produced by L. wollei is deoxy-CYN. The production of CYN and deoxy-CYN by L. wollei represents a potential human health risk and an additional source of these toxins in freshwaters. This is the first report of the production of CYN and deoxy-CYN by L. wollei or any species of the Oscillatoriales.
